Observing Summary:

The night began in remote mode with Cho operating from
Columbia.  The telescope spontaneously stopped tracking 
several times.  Starting and stopping the TCS didn't solve
the problem.  After a couple of hours it spontaneously
resumed tracking.  Very mysterious.  Halpern arrived at the 
observatory and took over operation locally at 11:30 pm.
At 12:30am, high humidity and low clouds forced closure
for 3 hours.  Opened again at 3:40 am.  Halpern closed the
dark hatch and filled the dewar.  There's a dead mouse in
the 1.3m kitchen. Tomorrow's operation will be from the
2.4m control room.
